Smart drag and drop user interfaces for print workflow system

A method comprising:

• accessing a memory that stores requirements for sequencing each of multiple activities available at a print shop into workflows;
• graphically presenting, at a Graphical User Interface (GUI), a workflow comprising an ordered subset of the activities to perform for processing a print job wherein each activity comprises an operation performed upon a physical print job by a printer or post-printing device;
• graphically presenting the available activities;
• detecting that a user is dragging an available activity onto the workflow;
• determining locations in the workflow where requirements for the activity are met while the activity is being dragged;
• operating the GUI to highlight the determined locations while the activity is being dragged;
• altering the workflow in response to detecting that a user has dropped the activity onto the workflow at a determined location.

A non-transitory computer readable medium embodying programmed instructions which, when executed by a processor, are operable for performing a method comprising:
